i use a tower air cooler and often face heat problems, so i wondered if the dram voltage of 1.35 is different from intel's standard 1.25. i think it might affect heat, and yes, i'm talking about memory dram voltage.

Stock RAM for DDR4 operates at 1.2 volts. RAM speeds above 2400 are generally considered overclocked, requiring 1.35 volts, especially when using an upgraded XMP profile. This is typical behavior. It's unlikely to significantly affect CPU heat production. The voltage needed to keep the multiplier stable is what primarily influences CPU temperature.

Stock ram DDR4 operates at 1.2v. RAMs faster than 2400 are usually overclocked and require 1.35v, which you achieve with a better xmp profile. That’s just normal. I’m not sure the voltage change affects CPU heat much. The core voltage needed for high multipliers is what raises temperature. Extra voltage means more power and heat in the system. As ambient rises, cooling efficiency drops. In this scenario, I wouldn’t expect more than a 1*C increase. Still it is

yea i have excellent cooling/case no water cooler but since faster memory timming dont really do a whole lot just wondered if the dram voltage effects cpu heat as somewheres it crosses the uncore and theres a memory controller inside the cpu but dont know if it effect the heat of cpu or not. isnt it that dram voltage over 1.35 can shorten the life of the cpu
